Structure, ordering, and bonding of half antiperovskites: PbNi3/2S and BiPd3/2S

Structure, ordering, and bonding of half antiperovskites: PbNi3/2S and BiPd3/2S

In a model study the crystal structures of shandite (Pb2Ni3S2), parkerite (Bi2Ni3S2) and their Pd homologues are investigated in terms of ordered half antiperovskites AM3/2S (A = Pb, Bi; M = Ni, Pd). This addresses fundamental questions on the structural relations, ordering and chemical bonding. Fro...

Zusammenfassung:In a model study the crystal structures of shandite (Pb2Ni3S2), parkerite (Bi2Ni3S2) and their Pd homologues are investigated in terms of ordered half antiperovskites AM3/2S (A = Pb, Bi; M = Ni, Pd). This addresses fundamental questions on the structural relations, ordering and chemical bonding. From crystal structure investigations a new cubic parkerite variant is presented for Bi2Pd3S2 that fits in an ordering model equivalently to shandite and parkerite...
